DETAILED DESCRIPTION

Referring now to FIGS. 1-2, one example of a step stool 10 is shown. Generally, the step stool 10 includes a step 12, having an upper surface 14, a front wall 16, a rear wall 18, and side walls 20, 22, the front wall 16, rear wall 18 and side walls 20, 22 being formed integrally with the upper surface 14 defining a cavity 24 on the underside of the step 12, as seen in FIG. 2. The step 12 includes two slots 26 therein, each slot 26 having a first end 28 formed in the upper surface 14 and a second end 30 formed in the rear wall 18, as seen best in FIGS. 10-13.

Step stool 10 further includes two front legs 32, 34, two rear legs 36, 38, and a handle 40. The two front legs 32, 34 may be connected to each other and are rotatably mounted to the step 12 such that they can be folded entirely within the cavity 24 on the underside of the step 12. In this example, the two front legs 32, 34 are connected to form a U-shape leg assembly 35, as shown in FIG. 14. The leg assembly 35 is rotatably mounted on the underside of step 12. As seen in FIG. 10, the underside of step 12 includes protrusions 41 extending therefrom, each protrusion 41 being formed with an indentation to receive the leg assembly 35 therein. In this example, two of the protrusions 41 include bore holes 42 for receiving screws or the like therein. A bracket 44 is placed over the leg assembly 35 and attached to the protrusions 41 via screws or the like thereby securing the leg assembly 35 to the step 12 as shown in FIG. 7.

Referring to FIG. 7, a first support brace 46 is pivotably connected to each of the front legs 32, 34 and to an extension 48 extending from the underside of step 12 in order to allow front legs 32, 34 to be pivoted between an open position, as shown in FIGS. 1-8, and a folded, closed position, as depicted in FIG. 9, with front legs 32, 34 folded entirely within the cavity 24 on the underside of step 12. The support brace 46 is preferably provided with an inverted Y-shape including an upper portion 50 and a lower portion 52. The upper portion 50 includes a first end 54 and a second end 56, and the lower portion 52 includes two lower arms 58 and 60. The first end 54 of upper portion 50 is pivotably connected to the extension 48 extending from the underside of step 12 in a conventional manner such as by rivets or similar means. The second end 56 of upper portion 50 extends between the two lower arms 58 and 60 of the lower portion 52 of the support brace 46. The second end 56 of upper portion 50 is pivotably mounted between the upper ends 62 and 64 of the lower arms 58 and 60, respectively, in a conventional manner such as by rivets or similar means that prevent the pivoting of front legs 32 and 34 outwardly from their open position. Lower ends 66 and 68 of lower arms 58 and 60, respectively, are pivotably mounted to front legs 32 and 34, respectively, in a conventional manner such as by rivets or similar means.

Handle 40 includes a middle portion 70 and two arms 72, 74 extending from either end of the middle portion 70 and generally perpendicular thereto as best seen in FIG. 15. The rear legs 36, 38 may be formed integrally with the distal ends of the two arms 72, 74 respectively or may be attached by any other well known means. The rear legs 36, 38 flare slightly outwardly from the two arms 72, 74 respectively. A grip 76 may also be included on the middle portion 70 of the handle 40 as seen in FIGS. 1-8.

Referring to FIGS. 1-8, the two arms 72, 74 of the handle 40 each extend through one of the slots 26 in the step 12 and terminate at the rear legs 36 and 38 respectively. The two arms 72, 74 are pivotably connected to the step 12 in a conventional manner such as by rivets or similar means such that the handle 40 can be rotated from an open position, as shown in FIGS. 1-8 to a closed position as shown in FIG. 9. In the open position, each arm 72, 74 of handle 40 extends primarily through the first end 28 of a slot 26 in the upper surface 14 of step 12 and is generally perpendicular to the upper surface 14. When the handle 40 is rotated to the closed position, each arm 72, 74 passes from the first end 28 of a slot 26 in the upper surface 14 to the second end 30 of the slot 26 in the rear wall 18. In the closed position, the handle 40 is generally coplanar with the step 12 and the rear legs 36, 38 are contained entirely within the cavity 24 on the underside of the step 12. Having the front legs 32, 34 and rear legs 36, 38 fold entirely into cavity 24 of step 12 and having handle 40 fold coplanar with the step 12 allows step stool 10 to have a smaller profile when in the closed position. This allows for easier storage and for more step stools to be store and racks or other merchandising setups for display and sale.

A second support brace 78 is pivotably connected to each of the rear legs 36, 38 and to the extension 48 extending from the underside of step 12 in the same manner as the first support brace 46 is connected to the front legs 32, 34 and the extension 48. The second support brace 78 is essentially the same as the first support brace 46 in design and operation and allows rear legs 36, 38 and handle 40 to be pivoted between an open position, as shown in FIGS. 1-8, and a folded, closed position with rear legs 36, 38 folded entirely within the cavity 24 on the underside of step 12.

Step stool 10 further includes pad 80 positioned on top of and attached to upper surface 14, as seen in FIG. 1. Pad 80 may be made of rubber or other suitable material and may have a raised or recessed pattern formed therein to provide a non-slip surface on the upper surface 14 of step stool 10.

Referring to FIGS. 1-8 and 19, step stool 10 further includes feet 82 on the ends of front legs 32, 34 and rear legs 36, 38. The feet 82 may be made of rubber or other suitable material to provide a non-slip gripping surface to prevent step stool 10 from moving when in use.

Referring to FIG. 20, step stool 10 may also include card 84 for providing text or pictures thereon. Card 84 may be made of cardboard or other suitable material and includes flaps 86 which are adapted to fit around arms 72, 74 of handle 40.
